Display additional dialog when application is in upgrade mode

I created a setup file which is working awesome.

Now whenever I rebuild an application without changing anything but Package Code is changed and then while I am going to install this version then a dialog will come "Upgrade Dialog" which ask me for upgrade an application.

Now in this situation I want to display an additional dialog created by me.

I am using the Insatllshield 2012 BASIC MSI project type.

Solution

  • I solved this problem.

    There are two properties exist in Installshield named "IS_MINOR_UPGRADE" and "IS_MAJOR_UPGRADE".

    When there is a minor upgrade at that time IS_MINOR_UPGRADE will set to 1. And same for Major upgrade.

    So using these properties, I can recognize the Upgrade mode.
